LABAN H. MURRAY, 0F SPRINGFIELD, OHIO, ASSIGNOB TO THE MURRAY-BLACK COMPANY, OF SPRINGFIELD, OHIO, A CORPORATION OF OHIO.

PAPER CUTTER.

Application filed May 23,

To all whom it may concern Be it known that I, LABAN H. MU RAY, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Paper Cutters, of which the following is a specification.

This invention relates to improvements in tools for cutting paper and the like, it more particularly relating to a tool known as a base board cutter used by paper hang-- crs for the purpose of trimming the wall paper about base boards, windows and the like, although the invention is applicable to other forms of cutters employing a rotatable cutting element.

The object of this invention is to provide an improved bearing for the cutting disk and supports for the same such that the disk may be prevented from wobbling by a simple adjustment of the bearing supports.

Referring to the drawings Fig. 1 is a side elevation of a tool embodying my improvements.

Fig. 2 is a top plan view of the same.

Fig. 3 is a section on the line 33 of Fig. 1.

Fig. i is a side view of the bearing.

Referring to the drawings, 1 represents a handle of any suitable form in which is secured in any suitable way a pair of slightly bowed arms 2 preferably of resilient materiahthe outer free ends of which are bent so as to lie in substantial parallelism. An adjusting screw 3 extends through the bowed portions oi the arms at a point in proximity to the handle and has a threaded connection therewith so that the distance between the free ends thereof may be adjusted. Located in aligned apertures in the free ends of 1921. Serial No. 471,846.

is slightly less in width than the hub of the disk so that the arms 2 may be caused to impinge more or less upon the faces of the disk about the hub thereof and thereby maintain the same in a true line relatively to the line of travel and prevent wobbling; the arms being readily adjusted by the screw 3. In assembling the parts, the disk is mounted on the bearing and the arms placed upon the trunnions and then afterwards secured in any suitable way in the handle.

Having thus described my invention, I claim:

1. In a tool or" the character described, a handle, a pair of bowed resilient arms secured in said handle, a bearing having trunnions mounted in the ends of the arms, a rotatable cutting disk mounted on said bearing, said bearing being less in width than the width of the disk, and an adjusting screw threaded in said arms.

2. In a tool of the character described, a, rotatable element, a support arranged on each side of said element, a bearing for said rotatable element having integrally formed trunnions loosely mounted in said supports, said bearing being slightly less in width than said rotatable element, and means for causing the support to hold said rotatable element in position on said bearing.

In testimony whereof, I have hereunto set my hand this 19th day of May 1921.
